Understanding the Find Minimum Time to Reach Last Room I Problem
Let's break down this LeetCode problem and understand what makes it challenging in interview settings.
Problem Statement
There is a dungeon with n x m rooms arranged as a grid. You are given a 2D array moveTime of size n x m, where moveTime[i][j] represents the minimum time in seconds after which the room opens and can be moved to. You start from the room (0, 0) at time t = 0 and can move to an adjacent room. Moving between adjacent rooms takes exactly one second. Return the minimum time to reach the room (n - 1, m - 1). Two rooms are adjacent if they share a common wall, either horizontally or vertically.

Get real-time assistance for Find Minimum Time to Reach Last Room I problems during coding interviews. Interview Coder provides instant solutions and explanations.
Examples
moveTime = [[0,4],[4,4]]6The minimum time required is 6 seconds. At time t == 4, move from room (0, 0) to room (1, 0) in one second. At time t == 5, move from room (1, 0) to room (1, 1) in one second.
moveTime = [[0,0,0],[0,0,0]]3The minimum time required is 3 seconds. At time t == 0, move from room (0, 0) to room (1, 0) in one second. At time t == 1, move from room (1, 0) to room (1, 1) in one second. At time t == 2, move from room (1, 1) to room (1, 2) in one second.
moveTime = [[0,1],[1,2]]3Constraints
2 <= n == moveTime.length <= 502 <= m == moveTime[i].length <= 500 <= moveTime[i][j] <= 109How Interview Coder Helps with Leetcode Problems
